But Teigen isn't only battling her own trolls. The model on Tuesday stepped up to defend the "Laguna Beach" star following the controversy connected to a photo she shared of her sons in swim truncks on the beach.

The internet expressed concern for the children and accused Cavallari of starving them instead of enjoying the patriotic, fourth of July Instagram post.

I will never know why parents criticize others so harshly, knowing they'd go insane if they were on the receiving end ALLTHETIME.

"I will never know why parents criticize others so harshly, knowing they'd go insane if they were on the receiving end ALLTHETIME," Teigen tweeted. "NO parent out there thinks they're perfect. I loathe these s---head commenters. Who would want to make someone feel horrible for fun?"

In April Teigen similarly earned the wrath of the internet for her parenting choices when she opted to go out to dinner with Legend a week after giving birth.

"I went out to dinner. People are pissed. Good morning!" she tweeted out in response before launching into a spree of snarky Twitter replies.

This also isn't the first time Cavallari has inspired backlash for her decisions as a mother — the MTV star in 2014 revealed she would not be vaccinating her sons.

"At the end of the day, I'm just a mom," she then said in defense on Watch What Happens Live. "I'm trying to make the best decision for my kid."
